Abstract: An electrolyzed water production system has a brine storage tank, brine supply means for supplying the saturated brine from the storage tank for mixing with raw water supplied from a source of raw water and an electrolytic cell for producing electrolyzed water. An electric control circuit comprises detection means for detecting the conductivity of the diluted brine supplied to the electrolytic cell, and feedback control means for controlling operation of the brine supply means in such a manner that the conductivity of the diluted brine detected by the detection means is adjusted to a predetermined target value.

Abstract: A production system of electrolyzed water of the type which includes a first brine tank arranged to store an amount of saturated brine, a second brine tank arranged to be supplied with the saturated brine from the first brine tank through an electrically operated pinch valve and fresh water from an external source of water through an electrically operated water supply valve for storing an amount of diluted brine, and an electrolyzer arranged to electrolyze the diluted brine supplied from the second brine tank for production of electrolyzed water.

Abstract: A brine supply system including a first brine tank to store diluted brine of a predetermined concentration to be supplied into an electrolytic brine treatment device and a second brine tank to store an amount of saturated brine at a predetermined concentration. When the level of diluted brine becomes a lower limit level, the first brine tank is supplied with fresh water from an external supply source of water until the level of diluted brine becomes an upper limit level and is intermittently supplied with a predetermined amount of the saturated brine from the second brine tank. Based on a previously memorized supply time of the fresh water, a supply frequency and a supply interval of the saturated brine for the memorized supply time are calculated to maintain the diluted brine at the predetermined concentration even when the first brine tank is being supplied with the fresh water.

Abstract: A production system of electrolyzed ion water wherein acid ion water and alkaline ion water are produced by electrolysis of water or brine between a pair of electrodes in an electrolyzer and discharged through discharge conduits for use in appropriate manner, and wherein DC voltage between the electrodes is inverted in polarity to eliminate contaminants adhered to the negative electrode in the electrolyzer. In the production system, invert ion water produced in the electrolyzer at a cleaning mode is discharged in such a manner as to be used as proper ion water, and the contaminants are eliminated without causing entry of the invert ion water into a storage tank of proper ion water.

Abstract: In an ice making machine the ice forming unit of which includes an upright ice forming plate located above a water tank and having a cooling surface in heat exchange relationship with an evaporator attached thereto and an ice forming surface to be supplied with water from the water tank by means of a water pump for forming the water into ice cubes, a first water supply conduit is connected to the water pump to supply the water from the water tank toward the ice forming surface of the upright plate when an ice making mode or a washing mode is selected at the ice making machine, and a second water supply conduit is arranged to introduce a portion of the water supplied from the water tank into a space above the evaporator only when the washing mode is selected at the ice making machine.

Abstract: An ice stock detecting apparatus includes a thermostat having a temperature sensor element and a holder for holding the sensor element in a spaced relationship with an ice stocker inner wall. The holder includes a pair of holding member fixedly mounted on the inner wall to project therefrom inwardly of the stocker, and a protecting member extending between the holding members. The holder supports the sensor element with downward inclination toward one end thereof. The protecting member has a top end portion disposed under the sensor element and inclined in a manner similar to the sensor element at a greater angle than the latter.
